Preliminary Hydraulics Webmap

The United States Army Corps of Engineers (USACE) HEC-RAS software was used to perform a hydraulic analysis of the existing channels in the Irondale Gulch watershed. The channels were originally analyzed with a one-dimensional hydraulic model. The channels that did not fully contain the 100-yr discharge were further analyzed with a two-dimensional hydraulic model. The map below displays the results of the two-dimensional analysis for the 100-yr event as a depth grid, a velocity grid, and a product grid (depth x velocity).

PLEASE NOTE that these results are preliminary and could change before this project is finalized.
